Test mode and output voltage can be set from the front panel or by a personal computer over an RS-232 link. The unitÕs internal EEPROM can be also programmed over the RS-232 for arbitrary waveforms. Examples included with the instrument are a two-tone output for IM distortion measurement and a tone-burst. Single quantity price is $289.00.
